HOSE-COUPLING- TOOL.

Application led Janaury 31, 1922, Serial No. 533,137.

To all whom t may concern.'

Be it known that I, RUDOLPH F. KnRBnN,

a citizen of the United States, residing at St. Cloud, in the county of Stearns and State of Minnesota, have invented certain nevvv and useful Improvements in Hose- Coupling Tools, of Which the following is a specification.

This invention relates to implements for applying the holding or clamping devices to hose couplings, and has for one of its objects to simplify and improve the construction and increase the efficiency and utility of de vices of this character.

Another object of the invention is to provide device of this character capable'of adaptation to hose and couplings of various sizes and forms Without material structural change. v

With these and other objects in vieiv the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative 25 of the preferred embodiment of the invention Figure 1 is a perspective view of the improved implement.

Figs. 2 and 3 are elevations of the im- 30 proved implement from different sides, one

of the figures being partly in section.

Fig. l is an elevation of the improved implement applied to atransverse section of a hose; illustrating the manner of using the implement.

Fig. 5 is a perspective view of one of the wire clamping members ready to be applied to a hose.

Figure 6 is a detached perspective view of the Wire binder element before being applied.

rEhe improved implement comprises a threaded stock 10 having a turning head 11 at one end and rotatably connected at the other end in a shoe or bearing member 127 the latternhaving a hollowed portion 13 at its free end to enable it to be retained upon an object such as a hose, Without slipping.

A nut device 14 engages the threads of the stock and is provided With trunnion like lateral projections 15.

The trunnions 15 are of uniform diameter throughout, or Without. enlargement at the ends as shown.

The Wire band which the improved implement is designed to apply to a hose, indicated at 16, to firmly bind it to a. rigid core, represented at 17, is initially formed as shown in Fig. 5 with loops 18 to engage around the hose and With the side portions 19 extended and terminating in eyes 20. The head or shoe 12 is then disposed between the loops 18 With its hollow portion 13 in contact with the hose, and the stock 10 rotated by the turning head 1l until the nut 14. is in position to enable the eyes 20 to be en gaged with the trunnions 15, as shown .in The head 11 is then rotated to cause the stock 1() to apply a strong pulling force upon the band to draiv it tightly around the hose, and when the band is sufficiently tight. the stock 10 is turned laterally toward the. position indicated by dotted lines in Fig. lto bend the side portions 19 around the connecting portion 21 between the loops 153 to form smaller loops engaging tightly around the portion 21. The surplus parts of the sides 1.9 are then cut off, and the implement together Withthe out off portions removed.

The trunnions 15 being of uniform diameter throughout, or Without enlargements at the ends, the eye portions 2O can be easily applied, and the surplus material after the severing at the completion of the clamping operation may be easily detached over the ends of the trunnions.

The improved device :is simple in conA struction, can be inexpensively mauufaon tured and of any suitable material and of any required size, and operates effectually for the purposes described.

Having thus described the invention, what is claimed as new is f device of the class described comprising a threaded stock having a turning head at one end and a shoe member at the other end in which the stock is rotatively mounted, and a nut engaging the threads of the stock and having laterally projecting trunnions adapted to receive a binding element.

In testimony whereof, I affix my signature hereto.

RUDOLPH F. KERBEN.
